River: poker meaning explained

What the river is in poker

Hold'em games deal five shared cards in three stages. First comes the flop, three cards at once; then the turn, a fourth card; and finally the river, the fifth. Each player combines their two hole cards with the five board cards to make their best five-card hand. Because nothing else is dealt after it, the river is the moment a draw either completes or misses. Players say a hand was 'rivered' when the last card turns a losing hand into a winner.

In a live dealing room, the dealer usually discards a burn card before the river. This glossary entry focuses on how the river works in house-banked casino poker, where you play against the dealer rather than other players.

The river in casino poker games

Wizard of Odds' Texas Hold'em Bonus rules (opens in a new tab) describe the sequence: two hole cards each, the flop, an optional Turn bet, the turn, an optional River bet, then the river. Winning Flop, Turn and River bets pay even money, and a tie pushes them all. In Ultimate Texas Hold'em, per Wizard of Odds' UTH page (opens in a new tab), the river brings your final betting decision if you checked twice: you put in 1x the Ante or fold.

River odds: how often a draw comes in

After the turn you have seen six cards: your two and the four on the board. That leaves 46 unseen cards. The cards that would complete your hand are called outs, and your chance on the river is simply outs divided by 46. In casino poker the dealer's hole cards are unseen too, so they count among the 46.

1. Count your outs: for a flush draw, 13 cards of the suit minus the 4 you can see leaves 9.
2. For the river alone, divide by 46: 9 ÷ 46 = 19.6%.
3. From the flop, find the chance of missing twice: (38/47) × (37/46) = 65.0%. Subtract from 100% to get 35.0%.

River example in Texas Hold'em Bonus

You play £5 Ante, add the £10 Flop bet and a £5 Turn bet, holding four hearts after the turn. Should you add a £5 River bet? The river completes your flush 19.6% of the time, but the bet wins whenever your final hand beats the dealer's, which can also happen without the flush. The overall game has a 2.037% house edge under Las Vegas rules, according to Wizard of Odds, and the Ante only pays even money with a straight or better; otherwise it pushes. No single river decision changes that long-run cost.

River myths in online poker games

A common complaint is that online games 'always' hit the dealer on the river. In UK-licensed RNG games the cards are drawn by a tested random number generator, and the final card is no more likely to help the dealer than you. Bad river cards feel memorable, which is why they seem common. Our page on how poker hands rank and the probability guide show how to work out your real chances.
